  		<p>This section describes the identifier conventions used by Intel&reg; Threading Building Blocks.</p>
</div>

  	<div class="section"><h2 class="sectiontitle">Case</h2>
  		<p>The identifier convention in the library follows the style in the ISO C++ standard library. Identifiers are written in underscore_style, and concepts in PascalCase.</p>
</div>

  	<div class="section"><h2 class="sectiontitle">Reserved Identifier Prefixes</h2>
  		<p>The library reserves the prefix <samp class="codeph">__TBB</samp> for internal identifiers and macros that should never be directly referenced by your code. </p>
